EM24
Introduction
EM24 is a three-phase energy analyzer for DIN-rail mounting, with configuration joystick, frontal selector and LCD display.
The direct connection version (AV2, AV9) allows to measure up to 65 A, the CT connection version (AV5, AV6) allows to measure up to 34875
A by means of current transformers (5 A secondary output).

Introduction
EM24 is organized in two menus:
• measurement and information menu: pages used to display the measurement pages, information relevant to the programmed parameters
and instrument firmware release
• settings menu: pages used to set parameters
Display
The display is divided into 3 lines.
Symbol Description
Displaying of phase-to-neutral system voltage

Displaying of max values
User ID
Displaying of system variables
Displaying of dmd variables
EEEE
Overflow.
Note: the DMD calculation, the hour-counter and the
energy meters functions are inhibited and the alarm
outputs are activated. The indication “EEEE” in a single
phase variable automatically implies the overflow condi-
tion of the relevant system variable, and the PF indica-
tion is forced to “0.000”.

Applications
Note: if an application with easy connection is selected, for the calculation of the active energy the power is always integrated, both in the case of imported
and exported power . The current direction does not affect the measurement. If an application without easy connection is selected, both the active imported
and exported are available.

Frontal LED and selector
Frontal LED
The frontal red LED flashes proportionally to the active imported energy consumption if the selector is in - 1 - 2 position, and to the reactive inductive
energy consumption in kvarh position. Any kind of negative (exported) energy will not be managed by the front LED.
Frontal selector
• Lock position: the frontal selector prevents from accessing the programming mode
• 1, 2, 3 (kvarh )position: quick access to measuring pages. Each position is associated with one measuring page according to the following table:
